NetServer NetServer Netserver Documentation HP Netserver High Availability SPOFless MSCS Cluster Solution Introduction This document profiles efforts in evaluating high availability cluster solutions ® ® managed by Microsoft Cluster Server in Windows NT 4.0 Enterprise Edition ® and Windows 2000 Advanced Server operating systems. The solutions evaluated are two-node clusters using redundant Fibre Channel Arbitrated Loop (FCAL) technology for the server to storage interconnect and are...
The host bus adapter used in all of our testing was the High Level View of Clustered Systems D8602A HBA. Public Network External Storage The Hewlett-Packard RS/12FC external storage subsystem was used for all configurations. Another storage subsystem could be used if it is on the Private ®...
white paper NetServer NetServer Netserver Documentation Redundant Fibre Channel Array Controllers SPOFless systems use redundant HP Fibre Channel array controllers. When a pair of these FC array controllers is installed into an RS/12FC storage cabinet, they operate on two redundant Fibre Channel loops.
Supported HP Solutions The SPOF Model The cluster solution based on the RS/12FC, which has been supported by Hewlett-Packard in the past, is known as SPOF. The SPOF solution uses a single Fibre Channel hub to connect two servers to an RS/12FC. A functional diagram of a SPOF cluster is shown below.

Subsections below only document the differences between a standard cluster installation and a SPOFless cluster installation.
